Abstract

A processing method for MS/AT when receiving 1x paging in a high-speed packet data network, comprising steps: after MS/AT transfers to HRPD network and notifies MSC through AN, if the paging information of 1x arrives, MSC passes AN sends a 1x service arrival notification message to the MS/AT, and carries the calling number in the message; when the MS/AT receives the 1x paging, it displays the calling number to the user and waits for the user's choice; if the user chooses to answer the 1x call call, MS/AT will terminate the business in HRPD network, switch to 1x and send a paging response message to 1x BS; if the user refuses to answer the 1x call, MS/AT will send a response message expressing user rejection to AN, indicating that the user cannot Answering the 1x call, after receiving the rejection message from the user, the AN constructs a paging response message and sends it to the MSC, informing the MSC that the call should be terminated. After receiving the rejection message from the AN, the MSC will terminate the call and release related resources. The present invention saves network resources and air link resources, and avoids unpleasant feelings brought to users.

Description

Processing method when dual-mode terminal receives 1x paging in high-speed packet data network

technical field

The present invention relates to a processing method when a code division multiple access 2000 1x (hereinafter referred to as cdma2000 1x) and high-speed packet data (hereinafter referred to as HRPD) dual-mode access terminal (hereinafter referred to as MS/AT) receives 1x paging in a high-speed packet data network .

Background technique

In practical applications, HRPD networks often appear in the form of joint networking with cdma2000 1x. Usually, cdma2000 1x networks are used to provide voice and low-speed data services, and HRPD networks are used to provide data-based services. Users use dual-mode terminals to connect enter. Logically, the cdma20001x network and the HRPD network are two mutually independent networks, and do not support information exchange between the two networks at the network side. With the development of technology, a connection link can be established between the two networks, so that call control and mobility management information can be transmitted between the two networks. For example, when the HRPD network adopts the network structure stipulated in 3GPP2A.S0008, a dedicated interface A1p can be established between the Mobile Switching Center (hereinafter referred to as MSC) of the cdma2000 1x network and the access network (hereinafter referred to as AN) of the HRPD network. To bear the call control and mobility management information between the MSC and the AN, the reference model of the HRPD interoperability structure after the A1p interface is established is shown in Figure 3. At this time, a dedicated logic interoperability module IWS (Interworking Solution) should be set in the AN, and the IWS is used to realize the conversion of the message on the A1p interface and the 3G1x service message on the air interface. This solution is called cross paging (CrossPaging) in 3GPP2. With the help of cross paging, when the user transfers to the HRPD network and notifies the MSC through the A1p interface, if a 1x paging message arrives at the MSC, the MSC will send the paging message through the cross paging mechanism, as shown in Figure 4.

The Paging Request (Paging Request) message sent by the MSC to the AN does not contain the calling number. Therefore, when the terminal under the HRPD network receives a 1x call, it cannot display the calling number to the user. After entering the 1x network and continuing the subsequent call process, the user can see the calling number. This problem can be solved by modifying the message content or message flow of A1p. For example, the function of the paging request (Paging Request) message can be extended, and a dedicated field can be added to carry the calling number. In the remaining part of this patent, the calling number is carried by extending the paging request message as an example for description.

After the 1x paging message with the calling number is delivered to the MS/AT under the HRPD network, the user can choose whether to answer the 1x call. When the user decides to reject the 1x call, if the MS/AT does not report the rejection information to the network, it will cause the MSC to resend the paging message in a wider range after a certain period of time. This resent paging message is Doesn't make sense, and creates the following problems:

1.1x waste of network resources;

2. Waste of HRPD network resources and air interface resources;

3. The user will repeatedly receive the rejected caller ID, which will affect the user experience.

Contents of the invention

In order to solve the above problems, the object of the present invention is to provide a processing method when MS/AT receives 1x paging in high-speed packet data network. According to this mechanism, after receiving the user's operation of accepting or rejecting the 1x call, the user's operation information can be transmitted to the MSC through the A1p interface through a specific message, so that the MSC can avoid subsequent unnecessary actions.

In order to achieve the above object, a processing method when a MS/AT receives 1x paging in a high-speed packet data network comprises steps:

a) When the MS/AT transfers to the HRPD network and notifies the MSC through the AN, if there is 1x paging information arriving, the MSC sends a 1x service arrival notification message to the MS/AT through the AN, and carries the calling number in the message ;

b) When MS/AT receives 1x paging, it displays the calling number to the user, and waits for the user's choice;

c) If the user chooses to answer the 1x call, the MS/AT will terminate the service in the HRPD network, switch to 1x and send a paging response message to the 1x BS;

d) If the user refuses to answer the 1x call, the MS/AT will send a response message expressing the user's rejection to the AN, indicating that the user cannot answer the 1x call. After receiving the user's rejection message, the AN constructs a paging response message and sends it to the MSC to inform the MSC The call should be terminated, and the MSC will terminate the call and release related resources after receiving the rejection message from the AN.

Detailed ways

The present invention mainly includes two processing situations when the MS/AT receives a 1x call in the HRPD network: the user chooses to answer the 1x call and the user refuses to answer the 1x call. The first subsection and the second subsection below describe these two types respectively. Condition.

1. User chooses to answer 1x call

Contains the following steps:

1) When the MSC receives an MS/AT call directed to its service domain, the MSC sends an extended paging request message to the HRPDAN, which carries calling number information. At the same time, the MSC sends a paging request message (Paging Request message) to one or more serving 1x BSs that the called MS/AT may contact. The paging request message may contain a virtual page indicator (Virtual Page Indicator: VPI) to inform the 1x BS that it is not necessary to send a General Page Message to the called MS/AT on the air interface. At the same time, start the T3113 clock for the paging request message, and the clock will stop after the MSC receives the paging response message.

2) The HRPD AN sends a 3G1X service packet including a General PageMessage to the MS/AT, and carries the calling number in the General PageMessage.

3) The user chooses to answer the 1x call.

4) The MS/AT switches to the 1x system and sends a page response message (PageResponse message) through the 1x access channel as a response.

5) 1x BS constructs a paging response message (Paging Response message), puts it into a complete layer 3 information message (Complete Layer 3 Information message), and sends it to the MSC. Subsequent processes are completed according to relevant 3GPP2 specifications. For the convenience of the user, the step of the user pressing the answer key in the subsequent steps can be omitted, and the terminal can be changed to automatic operation.

The operation process for the user to choose to answer the 1x call is shown in Figure 1.

2. The user refuses to answer the 1x call

Contains the following steps:

1) When the MSC receives an MS/AT call pointing to its service domain, the MSC sends an extended paging request message to the HRPD AN, which carries the calling number information. At the same time, the MSC sends a paging request message (Paging Request message) to one or more serving 1x BSs that the called MS/AT may contact. The paging request message may contain a virtual page indicator (Virtual Page Indicator: VPI) to inform the 1x BS that it is not necessary to send a General Page Message to the called MS/AT on the air interface. At the same time, start the T3113 clock for the paging request message.

2) The HRPD AN sends a 3G1X service packet containing a general page message (General PageMessage) to the MS/AT, and the general page message carries the calling number.

3) The user refuses to answer the 1x call.

4) The called MS/AT sends a response message indicating that the user refuses to the HRPD AN;

5) AN constructs a paging response message (Paging Response message), puts it into a complete layer 3 information message (Complete Layer 3 Information message), sends it to MSC, and notifies MSC to terminate the call. Subsequently, the subsequent called process is completed according to the relevant regulations of 3GPP2.

In the above step 4), the called MS/AT needs to send a response message indicating that the user refuses to the HRPD AN. The response message can represent user rejection information by extending a new field in the page response message (Page ResponseMessage), and send the page response message to the AN by including the page response message in the 3G1X service packet. It is also possible to utilize the reserved field in the 3G1X PacketAck (3G1X PacketAck) message, and specifically define a specific value indicating that the user refuses to answer in the reserved field. After AN receives the 3G1X packet confirmation message with specific value sent by MS/AT, it can confirm that the call has been rejected by the user.

In step 5) above, a field indicating user rejection may be added in the paging response message, and the AN notifies the MSC to terminate the call through the extended paging response message. It is also possible to notify the MSC to terminate the call by setting the radio environment and resource items in the paging response message as unavailable.

Figure 2 shows the operation flow of the user refusing to answer the 1x call.

3. About user choice

There are two ways for users to choose. One is each selection, when the MS/AT under the HRPD network receives a 1x call, the user should be prompted to select and display the calling number. Users can choose through the man-machine interface. If the user chooses to refuse, the prompt signal disappears and the HRPD service is not interrupted. The other is advance setting, the user can set MS/AT to reject or accept 1x calls in advance, which can be set for all calls or only for a specific number. When a 1x call arrives, the MS/AT operates according to user presets.
